ctdb-daemon: Exit if eventd goes away

Browse Source 
ctdbd enters a broken state if eventd goes away.  A clean shutdown is
not possible because that involves running events.  Restarting eventd
is possible but this might mask a serious problem and it is possible
that eventd might keep on disappearing.  Just exit.
